[0004] In the prior art, a folding plate is mainly formed by two plates hinged to each other to protect the foundation pit. The folding plate is placed on the ground for use. In strong wind weather, the folding plate structure formed by the two plates is easily blown down by the wind because the plate in contact with the ground lacks anchoring with the bottom surface, thereby losing the protective effect. There is room for optimization in the anchoring of the plate in contact with the ground.

[0005] To this end, we propose a foundation pit safety protection device. Utility Model Content

[0010] An extension component is arranged on the wall surface of the second protective plate for supporting and limiting the second protective plate. The extension component includes a rotating part, a sliding part, a positioning bolt and a locking hole. The rotating part is rotatably connected to the sliding part, the sliding part is slidably connected to the second protective plate, and a locking hole is provided on the wall surface of the second protective plate. The positioning bolt is threadedly connected to the rotating part. The rotating part can be flipped so that the positioning bolt faces the locking hole.
